Abstract

A sprocket (30) has a plurality of teeth (32) separated by roots (34) for cooperation with a chain (80) having links (82) connected by pins (84). The chain engaging surfaces of the sprocket are disposed so that different pitch radii are provided around the sprocket in a sequence that repeats for imparting tensions to the chain timed with respect to tension loads imparted to the chain from other sources whereby to reduce maximum chain tensions at one or more peak tension speeds.
